If you need to restore your device or ff you cannot remember the passcode, then you will need to restore your device using the computer with which you last synced it. This allows you to reset your passcode and re-sync the data from the device (or restore from a backup). If you restore on a different computer that was never synced with the device, you will be able to unlock the device for use and remove the passcode, but your data will not be present. Refer to Updating and restoring iPhone, iPad and iPod touch software.

Try restoring the iOS device if backing up and erasing all content and settings doesn't resolve the issue. Using iTunes to restore iOS devices is part of standard isolation troubleshooting. Restoring your device will delete all data and content, including songs, videos, contacts, photos, and calendar information, and will restore all settings to their factory condition.

If you can not restore your device then you will need to go to recovery mode.

Placing your device into recovery mode:

Follow these steps to place your iOS device into recovery mode. If your iOS device is already in recovery mode, you can proceed immediately to step 6.

1. Disconnect the USB cable from the iPhone, iPad, or iPod touch, but leave the other end

of the cable connected to your computer's USB port.

2. Turn off the device: Press and hold the Sleep/Wake button for a few seconds until the

red slider appears, then slide the slider. Wait for the device to turn off.

If you cannot turn off the device using the slider, press and hold the Sleep/Wake

and Home buttons at the same time. When the device turns off, release the Sleep/Wake

and Home buttons.

3. While pressing and holding the Home button, reconnect the USB cable to the device.

The device should turn on. Note: If you see the screen pictured below, let the device

charge for at least ten minutes to ensure that the battery has some charge, and then

start with step 2 again.

4. Continue holding the Home button until you see the "Connect to iTunes" screen.

When this screen appears you can release the Home button.

5. If necessary, open iTunes. You should see the following "recovery mode" alert:

6. Use iTunes to restore the device.

If you don't see the "Connect to iTunes" screen, try these steps again. If you see the "Connect to iTunes" screen but the device does not appear in iTunes, see this article and its related links.

Additional Information:

Note: When using recovery mode, you can only restore the device. All user content on the device will be erased, but if you had previously synced with iTunes on this computer, you can restore from a previous backup. See this article for more information.
